Description

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a system and method for ventilation based on a ventilation system,

The present invention relates to a ventilation system based on an outside-air dedicated system.

In recent years, the construction industry has become one of the trends of high-rise apartment houses with environment-friendliness and high energy performance due to high airtightness, high-temp shells, and high-efficiency heating and cooling systems. In particular, as interest in comfortable indoor air environment increases, it is becoming common to install a mechanical ventilation system of total heat exchange type for ensuring required ventilation for each generation. However, at present, it is difficult to form an effective indoor air environment due to the determination of the driving according to the subjective judgment of the residents, the concern about the increase of the electricity rate, and the inefficient operation of the user's operation of the environment apparatus.

In order to solve these problems, attempts have been made to apply Dedicated Outdoor Air System (DOAS), which is widely applied as a high efficiency central supply type ventilation system in North America and Europe, to a high-rise apartment house.

The air-conditioning system is a ventilation system that supplies air (supply air) supplied from outside the commercial building to the room by heating or cooling the pre-processed air through heat exchange with the exhaust discharged from the room to create a desired temperature and humidity condition . In other words, the centralized ventilation system adopting the external air-conditioning system separates the ventilating function and the indoor thermal environment control function, which were previously performed by the air conditioner, and the proper ventilation amount supply and indoor humidity control functions are controlled by the external air- The adjustment is carried out by a separate parallel system. For example, FIG. 1 is a view showing a concept of a central supply type ventilation system of a high-rise apartment house based on a conventional outdoor air-dedicated system.

The air conditioning dedicated system 100 adjusts the temperature and humidity of the supply air so as to take charge of the latent heat and some sensible heat of the room for supplying the air supply from the outside to the room according to the current ventilation amount standard, As shown in Fig.

If the sensible heat of the room is high, it may not be enough to maintain the proper temperature to the air supply volume only by the outside air dedicated system 10. Accordingly, the parallel cooling system 6, in parallel with the outside air dedicated system 10 in order to supplement the insufficient sensible heat or heating capability when the sensible heat in the room for the air supply supplied from the outside air dedicated system 10 is high, It is installed indoors.

However, although the conventional outside-air dedicated system can effectively reduce the load of the cooling coil, there is a problem in that it is not environmentally friendly in terms of using a conventional refrigerant-based cooling coil.

3 is a view schematically illustrating a configuration of a ventilation system based on an outside air dedicated system.

3, the ventilation system based on the outdoor air dedicated system includes a liquid type dehumidification system 100, an total heat exchanger 200, a cooler 300, an electric power supply 400, an air supply fan 500 and an exhaust fan 600 . Here, the liquid type dehumidifying system 100, the total enthalpy heat exchanger 200, the air supply fan 500 and the exhaust fan 600 serve as an outside air dedicated system, and the air conditioner 300 functions as a parallel cooling system .

The total enthalpy heat exchanger 200 dehumidifies and cools the outside air by exchanging the exhaust gas discharged from the room through the exhaust fan 600 with the outside air supplied from the outside. For example, the total enthalpy heat exchanger 200 may be a rotary enthalpy wheel, a passive desiccant wheel, or a membrane enthalpy exchanger.

The liquid type dehumidification system 100 dehumidifies the outside air passing through the total enthusiast exchanger 200 according to a predetermined humidity using a liquid type dehumidifier. Then, the dehumidified ambient air is supplied to the room through the air supply fan (500). For example, the liquid type dehumidifying system 100 may be a packed-tower bed type or an internally cooled dehumidifier type. In addition, a solid desiccant wheel may be applied.

The liquid type dehumidification system 100 can receive electricity from the electric power supply 400.

The liquid type dehumidifying system 100 will be described later in detail with reference to FIG.

The cooler 300 is a parallel cooling system that removes the sensible heat in the room. The cooler 300 performs indoor cooling by using a thermoelectric heat pump 310. The cooler 300 can receive electricity from the electricity supplier 400, and can supply heat generated by the cooling operation to the liquid type dehumidification system 100. For example, the cooler 300 may include a fan and a cooling coil, such as a fan coil unit, in addition to the thermoelectric heat pump 310, and generate a coolant using the thermoelectric heat pump 310 And the generated cooling water is applied to the fan and the cooling coil to perform indoor cooling. Also, the cooler 300 can generate hot water by heating the water using the thermoelectric heat pump 310, and supply the generated hot water to the liquid type dehumidification system 100.

6 is a view showing a thermoelectric heat pump.

Referring to FIG. 6, the thermoelectric heat pump 310 is a device using a Peltier effect. When electricity is supplied, heat is generated on one side of a module composed of N type and P type semiconductors, Is a solid type heat pump device in which heat is generated. For example, the thermoelectric heat pump 310 may be installed in a wall or a window of a building so that the heat absorption side is positioned toward the indoor side and the heat side is positioned toward the outdoor side, so that the sensible heat of the room can be removed. The heat generated on the heat-generating side may be supplied to the liquid type dehumidification system 100.

For example, FIG. 7 is a graph showing results of endothermic and exothermic experiments of a thermoelectric heat pump. As shown in FIG. 7, according to the endothermic and exothermic results of the thermoelectric heat pump 310, the surface temperature on the heat absorption side was measured to be about 15 ° C and the surface temperature on the heat emission side was measured to be about 45 ° C. Accordingly, the thermoelectric heat pump 310 performs indoor cooling to the heat absorption side, and heat can be supplied to the liquid type dehumidification system 100 on the heat generation side.

The electric power supply 400 supplies electricity to the liquid type dehumidification system 100 and the air conditioner 300. For example, the electric power supply 400 may include a fuel cell. Thus, the electric power supply 400 can supply the electricity generated in the fuel cell to the liquid dehumidification system 100 and the air conditioner 300.

FIG. 4 is a view showing another embodiment of the ventilation system based on the outside-air dedicated system shown in FIG. 3, and FIG. 5 is a view showing the construction of the ventilation system shown in FIG. 4 in detail. Hereinafter, a ventilation system based on an outside air dedicated system will be described with reference to FIG. 4, with reference to FIG. 5, and a description overlapping with FIG. 3 will be omitted.

4, the ventilation system based on the outdoor air dedicated system includes a liquid type dehumidification system 100, an total heat exchanger 200, a cooler 300, a solar energy system 410, an air supply fan 500, 600). Here, the liquid type dehumidifying system 100, the total enthalpy heat exchanger 200, the air supply fan 500 and the exhaust fan 600 serve as an outside air dedicated system, and the air conditioner 300 functions as a parallel cooling system .

Hereinafter, the liquid type dehumidifying system 100 and the solar energy system 410 will be described in detail with reference to FIG.

5, the liquid type dehumidification system 100 includes a desiccant storage tank 110, an absorber 120, a first sensible heat exchanger 121, a second sensible heat exchanger 122, A regenerator 130, a third sensible heat exchanger 131, a fourth sensible heat exchanger 132, and a cooler 140.

The dehumidifying agent storage tank 110 stores the liquid type dehumidifying agent and supplies the stored liquid type dehumidifying agent to the absorber 120 and the regenerator 130.

The dehumidifying agent storage tank 110 may be divided into a strong desiccant part 114 and a weak desiccant part 115. A water diffuser 111 is installed at a position where the concentrated portion 114 and the diluted portion 115 are divided to allow movement of water between the two portions. That is, as the concentration of the desiccant in the dense portion 114 and the dense portion 115 becomes constant due to the movement of the water from the portion 114 where the concentration is high through the water diffuser 111 to the portion 115 where the concentration is low, .

The first sensible heat exchanger 121 cools the outside air passing through the total enthalpy heat exchanger 200 by sensible heat using the cooling water supplied from the cooler 140.

The second sensible heat exchanger 122 is cooled by sensible heat exchange with the liquid type dehumidifying agent supplied from the dehumidifying agent storage tank 110 by using the cooling water supplied from the cooler 140.

The cooler 140 supplies cooling water to the first sensible heat exchanger 121 and the second sensible heat exchanger 122. For example, the cooling water supplied by the cooler 140 may be circulated through the first sensible heat exchanger 121 and the second sensible heat exchanger 122.

The absorber 120 dehumidifies and cools the outside air cooled by the first sensible heat exchanger 121 by using the liquid type dehumidifier cooled by the second sensible heat exchanger 122. That is, in the absorber 120, the liquid type dehumidifying agent is sprayed to the outside air to be supplied, whereby the outside air can be dehumidified. At this time, as the dehumidification is performed, the moisture of the liquid type dehumidifying agent is increased. The liquid type dehumidifying agent that has passed through the absorber 120 is supplied to the dense portion 114 of the desiccant storage tank 110 while the liquid type desiccant supplied from the desiccant storage tank 110 is supplied to the second sensible heat exchanger 122 and / And may be circulated through the absorber 120.

The third sensible heat exchanger 131 uses the heat supplied from the solar energy system 410 or the air conditioner 300 to heat the outside air supplied from the outside through sensible heat.

The fourth sensible heat exchanger 132 heats the liquid type dehumidifier supplied from the dehumidifying agent storage tank 110 by sensible heat using the heat supplied from the solar energy system 410 or the cooler 300.

For example, the hot water generated by the solar energy system 410 or the cooler 300 can be circulated through the third sensible heat exchanger 131 and the fourth sensible heat exchanger 132.

The regenerator 130 removes the moisture contained in the liquid type dehumidifying agent by spraying the liquid type dehumidifying agent heated by the fourth sensible heat exchanger 132 onto the outside air heated by the third sensible heat exchanger 131 to remove the liquid type dehumidifying agent Heat it. That is, the regenerator 130 can perform the role of regenerating the liquid type dehumidifying agent by removing the moisture of the liquid type dehumidifying agent whose moisture has increased through the absorber 120. The liquid type dehumidifier that has passed through the regenerator 130 is supplied to the dilute portion 115 of the dehumidifying agent storage tank 110 and the liquid type dehumidifier supplied from the dehumidifying agent storage tank 110 is supplied to the fourth sensible heat exchanger 132 and And may be circulated through the regenerator 130.

The solar energy system 410 supplies electricity to the liquid type dehumidification system 100 and the cooler 300 or supplies heat to the liquid type dehumidification system 100. For example, the solar energy system 410 may include solar heat accumulators, solar generators, solar generators, and the like. Thus, the solar energy system 410 generates hot water by heating the water using the heat obtained from the solar heat, supplies the generated hot water to the liquid type dehumidifying system 100, Can be supplied to the dehumidifying system (100) and the air conditioner (300).

The cooler 300 supplies the heat generated from the thermoelectric heat pump 310 to the liquid type dehumidification system 100. For example, the cooler 300 can generate hot water by heating water using heat generated from the heat generation side of the thermoelectric heat pump 310, and supply the generated hot water to the liquid type dehumidification system 100.

For example, as shown in FIG. 5, the solar energy system 410 and the thermoelectric heat pump 310 may be installed next to each other on a wall or a window of a building. At this time, the thermoelectric heat pump 310 is installed such that the heat absorption side is positioned toward the room and the heat side is located toward the outdoor side from the wall or window of the building, and the solar energy system 410 is installed in the building wall or window In the outdoor side. Therefore, the water is simultaneously heated by the heat generated by the solar energy system 410 and the thermoelectric heat pump 310 to generate hot water, and the generated hot water can be supplied to the liquid type dehumidification system 100.

8 is a flowchart showing a ventilation method of a ventilation system based on an outside air dedicated system.

In step S810, the total enthalpy heat exchanger 200 receives outdoor air from outside.

In step S820, the total enthalpy heat exchanger 200 dehumidifies and cools the outside air by exchanging the exhaust air discharged from the room through the exhaust fan 600 with the outside air supplied from the outside.

In step S830, the liquid type dehumidification system 100 dehumidifies the outside air passing through the total enthusiast exchanger 200 using a liquid type dehumidifier according to a predetermined humidity. That is, the absorber 120 of the liquid type dehumidification system 100 dehumidifies and cools the outside air by spraying the cooled liquid type dehumidifier on the outside air using the cooler 140. [ At this time, the regenerator 130 of the liquid type dehumidification system 100 is operated by the heat of the thermoelectric heat pump 117 included in the cooler 300 or the heat of the liquid type dehumidifier Thereby removing the moisture contained in the liquid type dehumidifying agent and heating the liquid type dehumidifying agent.

For example, the thermoelectric heat pump 310 may be installed in a wall or a window of a building so that the heat absorption side is positioned toward the indoor side and the heat side is positioned toward the outdoor side, so that the sensible heat of the room can be removed. The heat generated on the heat-generating side may be supplied to the liquid type dehumidification system 100.

For example, the solar energy system 410 and the thermoelectric heat pump 310 may be installed together in a building wall or window. At this time, the thermoelectric heat pump 310 is installed such that the heat absorption side is positioned toward the indoor side and the heat side is positioned toward the outdoor side from the wall or window of the building, and the solar energy system 410 is installed to the outdoor side . Therefore, the water is simultaneously heated by the heat generated by the solar energy system 410 and the thermoelectric heat pump 310 to generate hot water, and the generated hot water can be supplied to the liquid type dehumidification system 100.

In step S840, the outside air dehumidified by the liquid type dehumidification system 100 is supplied to the room through the air supply fan 500. [

In step S850, the parallel cooling system removes sensible heat in the room. Here, the parallel cooling system performs indoor cooling using the thermoelectric heat pump 310.

In step S860, exhaust is discharged from the room through the exhaust fan 600. [ At this time, the exhaust is discharged via the total enthalpy heat exchanger (200).
